Ok thanks! Erick I downloaded the FLIP from ATMEL I'm going have to build a cable for this because on my PCB I have connections to RXD, TXD, PSEN and RESET on th uc, and for autoisp I need to connect PSEN to RTS and DTR to RESETand this pins are 12v high rigth?

I know I'll need a MAX232 to get RXD and TXD from RS232 convert to TTL levels. Can I get a cable for this or I'll need to build my own?

Now for the NoTouch I need to find the link but my question is this my sotfware is very large and is in assemnbler what I need to do with this software caopy as a subroutine or I just loaded in a diferent add of the uc?

Thanks again for your help!
